Quick Scoop: How old is Elon Musk’s daughter?

When people online ask “how old is Elon Musk daughter,” they’re usually talking about Vivian, his transgender daughter who changed her name and distanced herself from him. She was born in Los Angeles on April 15, 2004, so she turned 21 in April 2025 and will turn 22 in April 2026.

However, Musk actually has several daughters, not just one:

  • Vivian Jenna Wilson (with Justine Musk) – born April 15, 2004 → 21 years old now.
  • Exa Dark Sideræl “Y” (with Grimes) – birth announced December 2021, via surrogacy, so she is about 4 years old now.
  • Arcadia (with Shivon Zilis) – born February 28, 2024, so she just turned 2 in 2026.

So depending on which daughter you mean, the age changes, but the most commonly searched one, Vivian, is 21.
